nection for the supporting'legs, w ich is' easy and inexpensive to construct and WlllCll will actautomaticall tolock the legs inextended position an automatically unlock itself when the weight of the bed frame is the bed.

One form which my invention may assume is exemplified by the following described illustration in the accompanying g drawings in which Fig. 1 shows a vertical,

sectionalview of the outer part of a fold- =-ing bed '.i-llu st r'ating a supporting leg in ig. 3' shows a secfolded position. Only so much of a bed frame as is necessary to an understanding of the present invention has been illustrated. This, bed frame includes side rails 10 pivao otally mounted at their forward. ends for folding movement and carrying at their outer end a rigid footpiece 11. portinleg 12 is connected to each side rail jfor f0 ding. movement. The hinge connection between the leg and side rail embodies the following construction: the upper end of each leg is flattened, as shown at 13, and into this flattened portion a longitudinal slot 14 and a transverse slot 15 are out.

Thrqugh these slots extends a rectangular I hinge pin 16 fixed to the side rail 10, or other part of the bed frame. The roctan gular slot 14 is somewhat longer than the pin 17 and when the bed is extended and the leg 12 is restin on the floor and in alignment with the cot piece 11, the hinge pin 16 will seat in the bottom 'of the slot 14- by reason of the weight imposed thereon by the bed frame. A segment 17 is cut so away between the slots at t e upper inside corner and a. similar segment 18 is cut away 1 .between the'slots at the lower outside cor-= ,ner except that the last named segment terminates short of the bottom longitudinal arrangement of the several parts above A sup-1 the hinged members, the other member hav 7 slot so that when the hinge in 16 is seated in the-bottom of the slot, t e leg is locked against swinging movement. To enable the leg to be folded, the bed frame must first be raised-to allow the hinge pin 16 to move to the nppenend of the ion 'tudinal slot, whereupon the leg will be ree to swing inwardly to folded position.

The present hinge is easy and inexpensive to construct and acts automatically to lock the leg against movement of any kind when the bed frame is'extended. Therefore the leg will be held against accidental disp acement.- Likewise, when the wei ht 0f the bed is removedfrom the legs an the latter are isuspended from the bed frame in the act of foldin" the bed, the hinge connection is automatically unlocked so thatthe legs are free to swing to folded position.

Various'changes in the construction and I6 shown and described may be employed without departing from the spirit of my invention as disclosed in the appended claims. v

" Having/ thus described my invention, what I claima'ndidesire to secure by Letters Patent is; i

1-. A folding lied comprising a frame ivota lly mounted at one end for -fol ing movement, a pendant supportin leg at the opposite end of the frame and a.hinged connection between the leg and frame comprising a pin elongated in the direction of the axis of the leg and flied upon one of ing vertical and horizontal slots crossing each other. the material at the upper inside corner and the lower outer corner between' the cross slots being cutaway to allow the pin to turn therein through an arc of ap-- proximately 90 when the le is hanging pendant and the vertical slot being exten ed slightly at one end to form a pocket 01' seat for the pin whdn the frame is resting on the leg "whereby to lock the leg against swinging movement. 2.
